My earliest Eurovision memory is "Hemel en Aarde" representing us in 1998. The first edition I saw in full was 2005 in Kyiv and funny enough the first Eurovision I went to was 2017 in Kyiv as well! A wonderful and unique experience.
To me the most beautiful entry ever is 'Lejla' in 2006 and the best winning song 'Euphoria', but ‘1944’ is a close second!
